recognized java environment at startup page, but not shown in 「java management」page

The problem happens when some java versions have been locally installed (or downloaded) at startup, the temporal database doesn't record the java version list at all!
Thus, after installation, at "java management" page, you can't see the newly installed version at all!

Solution:

• Migrate the data to the formal database
• redesign java management page so that the global installed java (e.g. /usr/bin/java) could be recognized as well.
